Mario: Could you please look at this patch series? It touches gdsys board and for future gdsys board should be converted to use u-boot driver model API...

This patch series removes gdsys's board_pex_config() function by converting it to spl_board_init(), adds a new mvebu-reset driver for enabling / disabling PCIe ports and finally moves PCIe code from serdes driver to pci_mvebu.c driver.
After all these changes, PCIe link is not initialized in serdes code anymore, but in pci_mvebu.c driver with help of mvebu-reset driver.
I'm not sure if change for gdsys board is correct, so if somebody has this board, please test it.
I tested this change on A385 board Turris Omnia and I verified that PCIe links are really enabled by pci_mvebu.c driver and not before.
This patch series is based on u-boot-marvell/next branch.
